T 0 all whom it may concern; v Be it known that we, CHARLES W. Gross and Join; A. Learn, citizens of theUnited States, residinggat Napa in. the count-y of Napa and State of California, have invent- .ed certain new and useful. Improvements in Elevators, of which the following is'a specification 1 jg I This invention relates toielevatorsspecially adapted for usein connection .withthe radiators of motor cars.

This invention. consistsgin the novelconstruction and combination vofgthe parts hereinafter fully describedand claimed whereby the radiator is raised, lowered and positioned.

Fig. 4 is a detail view of one of the pivoted arms ,ofthetilting frame. 7 Fig. 5'isa; cross-section ou line 55 in Fig.3. i

A suitable supporting base 6 is provided, and is stood in the botto nofa testing tank 7 which is adapted to contain water. A bracket 8 projects from one end portion of the base, and 9 and 10 are upper and lower forked arms which are pivoted at one end to the bracket by pins 12 and 14, and which form a parallel motion device. A vertical block 15 is pivoted by pins 16 to the freeend portions of the arms 9 and 10 and is held in a vertical position by the parallel motion device when raised and lowered. The block 15 is raised and lowered by means of a lever 17 secured on a rock-shaft18 which is journaled in bearings 19 on the base 6. J

This rock-shaft lever 17 is pivoted to one end of a connecting-rod 20 by a pin 21, and

the other end of the connecting-rod is piv-- oted to the upper arm 9 by a pin 22. The rock-shaft 18 is operated by a hand lever 25, and 26 is a pawl pivoted to the hand lever and engaging-with a notched plate 27.

A serrated or corrugated surface .13 is a gationsv prevent 1 the turntable "from moving I i the radiator from sliding off the frame when the frame is tilted as shown in ,Fir. 2. These arms 34 have longitudinal slots 36 which are slidalileover the pivot pins "'35, and stop brackets 37 are secured to the frameand ensd gage with the lreegend portionstot the pins.

lVhen the arms. are turned towards each other, as. shown in Fig. 1, they are-support ed'bythe stop brackets in the same plane as v the frame 32, but they may be 'moved .up-

A shaft; 45 is journaled in lugs 46 on the underside of the turntable, and has an operating handle 47 at one end. Arms 48 are secured on the shaft 45, and are pivotedto the releasing bars 43 bypins 49. When the releasing bars are raised by turning the shaft 45, both pawls 41 are disengaged simultaneously, and the tilting frame can be lowered to any less inclination'with This elevator device enables a mechanic to make all the necessary repairs or changes to a radiator without removing it from the elevator.

hat We claim is:

1. In an elevator, a support, a parallel motion device pivoted to the support, avers tically movable work support carried by the parallel motion device, and means for operating the said device to raise and lower the work support.

2. In an elevator, a support, a parallel motion device pivoted to the support, a vertically movable blockcarried by the parallel motion device, a revoluble work support provided with a vertical pivot which connects it with the said block, and means for operating said device to raise and lower the said block and work support.

3. In an elevator, a support a parallel motion device pivoted to the support, a vertically movable block carried by the said device, aturntable pivoted to the said block, a tilting frame for supporting the work pivoted to the said turntable, and means for operating the said device to raise and lower the work support.

4. In an elevator, a support a vertically movable block carried by the said support, a turntable pivoted to the said block, a tilting frame for supporting the work pivoted to the said turntable, and means for raising and lowering the said block.

5. I an elevator, a support,a vertically movable block carried by the said support, a turntable pivoted to the said block, said block and turntable being provided with friction contact surfaces which pre vent the turntable from moving too freely, a tilting frame for supporting the work pivoted to the said turntable, and means for raising and lowering the said block.

6. In an elevator, a support, a vertically movable block carried by the said support,

a. turntable pivoted to the said block,

tilting frame for supporting racks secured to the turntable,

with the toothed racks and supporting the frame at various angles, means for releasing-the said p'awls,simultaneously to lower.

tilting frame for supporting the work pivoted to the turntable, means for supporting'the said frame from the turntableat thework pivoted to the turntable, toothedv pawls pivoted to the said frame and engaging various angles, and means for raising and II lowering the said block.

' 8. In an elevator, a support, a vertically" movable block; carried by the said support,

a turntable pivoted to the said block, a

tilting frame for supporting the. work pivoted to the turntable, arms pivotally connected to the frame adjacent to its pivots and operating to retain the worklon' the frame when tilted, and means for r'ais-' ing and lowering the said block. I

9;In an elevator, a support, parallel motion iarm pivoted tothe'support at one end and arranged one above the other, a

vertically movable work support carried by the free end portions of the said arms,; a'=' rock-shaft journaled in the support under the said arms, a lever secured on the rockshaft, a connecting-{0d between the said lever and the upper parallel motion arm, and means for, operating therockshaft to raise and lower the worl support.v

In testimony whereof we afiiii oursigf natures.
